One of the benefits of modern refrigerators, especially LG models, is their capability to dispense both ice and chilled water. However, a common issue many users face is when the ice maker functions perfectly, but the water dispenser refuses to cooperate. If you find yourself grappling with this conundrum, don’t worry! In this comprehensive guide, we’ll delve into the possible causes of your LG fridge’s water not working while the ice continues to flow. Additionally, we’ll provide effective troubleshooting tips and maintenance strategies to help you get back to enjoying crisp, refreshing water on demand.
Understanding the Core Components of Your LG Fridge
Before diving into troubleshooting, it’s essential to understand how the water and ice dispenser system works. The LG fridge is equipped with several core components, each playing a vital role in ensuring the efficient delivery of water and ice.
The Water Supply Line
The water supply line is the pathway through which water travels from your home’s plumbing to the refrigerator. If this line is compromised, it will affect the water dispenser but not the ice maker, which uses a separate reservoir to freeze water.
The Water Filter
An often-overlooked component is the water filter. The water filter removes impurities, odors, and tastes from the water supply. If the filter is clogged or malfunctioning, it can restrict water flow to the dispenser.
The Water Inlet Valve
The water inlet valve controls the flow of water into the ice maker and water dispenser. If this valve is faulty, it may allow enough water for ice production but not enough for the water dispenser.
The Dispenser Switch
The dispenser switch is responsible for sending the signal to release water when you press the lever. If this switch is defective, the water dispenser will not operate even if everything else is functioning correctly.
Common Reasons for Water Malfunctioning
Let’s break down some common reasons why your LG fridge’s water dispenser may stop working while the ice maker continues to churn out ice.
1. Clogged Water Filter
Clogged filters can severely restrict water flow, impacting the performance of your water dispenser. If you notice that your water doesn’t dispense but ice continues to function, the first thing to check is the water filter.
2. Frozen Water Supply Line
Another critical reason for the water malfunction could be a frozen water supply line. If the temperature setting in the fridge or freezer is too low, it can cause the water line to freeze, blocking water flow.
3. Faulty Water Inlet Valve
A malfunctioning water inlet valve might be partially blocked or clogged, allowing ice to be formed while preventing water from dispensing. Testing its functionality is crucial for water issues.
4. Defective Dispenser Switch
A bad dispenser switch can lead to issues with the water dispenser not functioning properly. If you press the lever and hear no clicking sound, this may very well be the source of your problems.

What should I check first if my LG fridge dispenses ice but not water?
When your LG fridge offers ice but not water, the first thing to check is the water supply line. Ensure that the line is not kinked, twisted, or damaged, as this could restrict water flow. Additionally, verify that the water shut-off valve is fully open. If the supply line appears to be in good condition and the valve is open, the next step is to check the water filter.
The water filter might be clogged or need replacement. A clogged filter can impede water flow to the dispenser, resulting in no water output. Check the owner’s manual for the proper procedure to replace or clean the filter, and consider replacing it if it’s been over six months since the last change. If issues persist even after changing the filter, further investigation may be necessary.
How do I know if the water filter is clogged?
To determine if your water filter is clogged, start by checking the water dispensing rate. If the water comes out slowly or is completely absent while the ice maker functions normally, it could indicate a blockage. Another sign of a clogged filter is a change in taste or odor of the water, suggesting that impurities are not being adequately filtered.
To further verify the condition of the water filter, you can try turning off the water supply to the fridge and then disconnecting the filter. If water flows freely from the filter bypass plug, the filter is likely clogged and needs to be replaced. However, if water does not flow, the issue may lie with the water supply line itself.
What can cause the water line to freeze?
Frozen water lines can be a common problem in refrigerators, including LG models. This can occur if there is a cold air leak in the refrigerator’s insulation or if the temperature settings are too low. If the fridge is positioned in a location that experiences extreme cold, this could further contribute to the freezing of the water line.
To address frozen water lines, first adjust the temperature settings to a warmer range. Inspect the fridge and freezer compartments for any signs of ice build-up, particularly around the water line areas. If necessary, unplug the fridge to allow the water line to thaw, and check for proper airflow to ensure the temperature remains stable moving forward.
What if the water filter indicator light is not on?
If your LG fridge’s water filter indicator light is not illuminated, it indicates that the appliance does not recognize a need for a new filter. This doesn’t always mean the filter is functioning properly. If you’ve recently noticed a decrease in water flow, it may still be worth replacing the filter regardless of the indicator light status.
Sometimes the indicator light can malfunction or fail to reset after a filter change. You can manually reset the indicator by following the instructions in your refrigerator’s user manual. If you’ve replaced the filter and the indicator remains off while experiencing issues, the filter itself could be a quality concern or there might be another underlying issue with the refrigerator.
How do I reset my LG fridge’s water dispenser?
Resetting your LG fridge’s water dispenser can often resolve issues with low water flow or a non-functioning dispenser. To reset it, locate the control panel and find the appropriate buttons for the water dispenser. Generally, holding down the “Dispenser Lock” or “Water” button for several seconds can trigger a reset.
After resetting, test the water dispenser to see if it functions correctly. If problems persist, turn off the refrigerator for a few minutes and then turn it back on. This can help clear any error codes or glitches that may affect the dispensing function. If the issue continues, you may need to investigate potential problems with the water valve or electronics further.
What should I do if the water pressure is too low?
If the water dispenser is producing water but at a low pressure, it could be due to inadequate water flow from your household supply. Check the home’s water pressure when using other appliances to confirm whether it’s a broader issue. If the water pressure in your home is low, consider contacting a plumber to assess the situation.
Additionally, a partially closed water valve in your fridge can also contribute to low water pressure. Inspect the fridge’s water supply line connection to ensure the valve is fully open. Moreover, if the refrigerator is connected to a long or convoluted water line, it may also resist proper water flow, necessitating a direct connection or repairs to that line.
Why is my fridge making noise when trying to dispense water?
If your LG fridge is making unusual noises while attempting to dispense water, it could indicate a problem with the water inlet valve. Noises such as humming, buzzing, or rattling may suggest that the valve is malfunctioning or obstructed. Sometimes, foreign objects can fall into the water line, causing clogging and resulting in noise.
In such cases, it’s advisable to turn off the appliance and inspect the water line and inlet valve for visible issues or obstructions. If everything appears normal but the noise persists, it might be necessary to replace the water inlet valve or consult a professional technician to diagnose the problem more thoroughly.
Can I use the ice maker while the water dispenser is not working?
Yes, you can typically continue using the ice maker even if the water dispenser is not functioning. The ice maker operates primarily reliant on the same water supply that fills the dispenser; however, it is designed to freeze water into ice cubes and may not face the same immediate issues as the water dispenser.
While using the ice maker, keep in mind that if the water supply problem is due to a plumbing issue, this may eventually impact the ice production as well. It’s advisable to address the underlying cause related to the water dispenser to ensure continued functionality of both the ice maker and water dispenser in your LG fridge.
